Haemorrhagic septicaemia (HS) is the most economically important disease caused by Pasteurella multocida. The organism causes a wide range of diseases in domestic animals throughout the world. In India, HS has been reported to be the most fatal of five important epizootic diseases affecting buffaloes and cattle caused by serotype B:2. Outer membrane protein (OMP) of gram negative bacteria plays an important role in disease process as it acts at an interface between the host and pathogen. Protein H (OmpH) is the major OMP in the envelope of P. multocida, is protective and has a potential as a vaccine candidate.
